Article R613-44-2 of the French Intellectual Property Code

Any opposition filed by the owner of the contested patent shall be declared inadmissible.

Any opposition that does not comply with the provisions of Articles R. 613-44 or R. 613-44-1 shall also be declared inadmissible.

Where an objection is based on more than one ground, it shall be admissible only if the statement accompanying it complies, for at least one of these grounds, with the provisions of 3° of Article R. 613-44-1. It is deemed to be unfounded on grounds that do not satisfy this condition.

In the event of automatic inadmissibility, the Director General of the National Institute of Industrial Property shall notify the opposing party of the irregularities. The opposing party is then given a period in which to contest this inadmissibility or, in the case of the power of attorney provided for in 5° of Article R. 613-44-1, to put his application in order. In the absence of well-founded observations or regularisation, the objection is declared inadmissible.

The decision of inadmissibility is final.
The decision of inadmissibility is entered in the National Patent Register.

Article R613-44-2

Est déclarée irrecevable toute opposition formée par le titulaire du brevet contesté.


Est également irrecevable toute opposition qui n’est pas conforme aux dispositions des articles R. 613-44 ou R. 613-44-1.


Lorsqu’une opposition est fondée sur plusieurs motifs, elle n’est recevable que si la déclaration l’accompagnant satisfait, au moins pour l’un de ces motifs, aux dispositions du 3° de l’article R. 613-44-1. Elle est réputée non fondée pour les motifs qui ne satisfont pas à cette condition.


En cas d’irrecevabilité relevée d’office, le directeur général de l’Institut national de la propriété industrielle notifie les irrégularités à l’opposant. Un délai est alors imparti à ce dernier pour contester cette irrecevabilité ou, dans le cas du pouvoir du mandataire prévu au 5° de l’article R. 613-44-1, pour régulariser sa demande. A défaut d’observations fondées ou de régularisation, l’opposition est déclarée irrecevable.


La décision d’irrecevabilité est inscrite au Registre national des brevets.
